FastRoute

This library provides a fast implementation of a regular expression-based router. Firstly, while writing a PHP extension is obviously a lot of fun, it is unlikely to be particularly beneficial in terms of performance unless the code involves computations in tight loops. Porting “normal” components like routers to C is usually a big waste of time. You can get much better results by doing a few small improvements on the algorithmic side. For the same reason I’m not a big fan of things like Phalcon, i.e. PHP frameworks written as a C extension. You can get good performance by using an appropriate application design (that is not massively overengineered) and still retain the flexibility of keeping everything in PHP. A URI is dispatched by calling the dispatch() method of the created dispatcher. This method accepts the HTTP method and a URI. Getting those two bits of information (and normalizing them appropriately) is your job.
